.MACHINE FOR TREATING HIDES, SKINS, AND LEATHER.

Application filed August 17, 1907.

To all whom it may concern:

Be it known that we, FRANKLIN J. PER- KINS, of Woburn, county ofMiddlesex, and State of Massachusetts, and JOHN WV. SMITH, a subject ofthe King of Great Britain, but now residing in said Woburn, haveinvented an Improvement in Machines for Treating Hides, Skins, andLeather, of which the following description, in connection with theaccompanying drawings, is a specification, like letters on the drawingsrepresenting like parts.

This invention relates to apparatus for treating hides, skins andleather, and is herein shown as embodied in an apparatus especiallyadapted for unhairing, working-out, fleshing etc.

The present invention has for its object to provide a machine orapparatus which is easy to operate and with which a maximum number ofhides or skins can be effectively treated in a minimum time.

The particular features of the invention will be pointed out in theclaim at the end of this specification.

Figure 1 is a front elevation with parts broken away of a machineembodying this invention; Fig. 2 a side elevation of the machine shownin Fig. 1 looking toward the right. Fig. 3 a side elevation of themachine shown in Fig. 1 looking toward the left. Figs. 4 & 5 details tobe referred to. Fig. 6

a vertical section with parts omitted, taken on the line 6 6 Fig. 1.Fig. 7 a detail of one of the working rolls or tools. Fig. 8 a detailin. section and elevation to be referred to. Fig. 9 a detail of thecrank shaft for positioning the bed. Figs. 10 & 1.1 details to bereferred to, and Fig. 12 a detail in plan of the driving mechanism to bereferred to.

In accordance with this invention, the machine or apparatus is providedwith a plurality of working tools, herein shown as four in number andeach comprising 'a cylinder or roll it provided with blades, ribs, vanesor working edges 1), which are helically arranged and extend in oppositedirections from a point intermediate the ends of the roll toward itsopposite ends.

Each working roll is designed to move in a fixed circular path, and alsoto have a rotary motion about its own axis. For this purpose, the rolls.a are mounted in journal boxes 0 d secured to a carrier in the form ofwheels or frames e,f, see Figs. 6, 7 8t 8, which are keyed or otherwisefastened to a sleeve Specification of Letters Patent.

g, loose on a shaft 71., which is journaled in upright side frames 2',i, and in an auxiliary side frame or support 7c.

The sleeve is rotated on the shaft h as will be described, and thisrotation produces bodily movement of the rolls a in a circular path. Therolls a are also simultaneously revolved about their axis a, which isaccomplished as herein shown by providing each roll a with a pinion m,see Fig. 7, which meshes with a large gear n, see Fig. 2, keyed orotherwise fastened to the shaft h, see Fig. 8.

The shaft 7L and the sleeve g are driven from a main shaft 15, which maybe accomplished by mechanism as will now be described.

The main shaft 15 is provided as shown with a driving pulley 16 and witha substantially long pinion 17, which meshes with a gear 18 keyed orotherwise rendered fast on the sleeve 9; see Figs. 8 & 12 and also witha substantially long intermediate gear or pinion 19 on a shaft 20,suitably supported in the frame work of the machine, the pinion 19meshing with the gear 21 fast on the shaft h. It will thus be seen thatthe working rolls and their carrier are rotated in the same directionbut at different speeds and are driven from the main shaft 15.

The working rolls a in the revolution of their carrier, are designed tobe brought into engagement with a hide or skin on a suitable bed,represented in the present instance as an endless band or apron 25, ofrubber or other elastic or flexible material, which is movable towardand from the path of movement of the rolls a, and in the presentinstance said apron is passed about a lower roller 26, see Fig. 2,journaled in boxes 27 which slide in slots 28 in suitable bosses 29attached to the side frames of the machine; see Fig. 1, and areyieldingly held at the lower end of said slots by springs 80, whosetension or pressure is regulated by adjusting screws 31 see Fig. 2. Thebed or apron is also passed about an upper roller 32, j ournaled inboxes 33 carried by the upper end of the levers 34, which are pivoted attheir lower ends to the side frames of the machine. The levers 34 arejoined together by a tie rod 35, which forms a pivotal connection forthe upper end of links 36, preferably extensible and pivotally connectedat their lower ends to cranks 37 on a shaft 38, journaled in theframework of the machine and adapted to be intermittently rotated, anddesigned to be rotated a half turn,

position and to leave it there, until the said shaft is given anotherhalf turn in the same direction to move the bed back into its startciening or inoperative position. This intermittent rotation of the crankshaft 38 may be effected from a continuously rotating shaft 39 at thewill of the operator. For this purpose we have provided a clutchmechanism, comprising two members 40, 41, one of which as 40 is fast onthe shaft 39, and is made in the form of a disk which is provided on itsface with teeth 42, see Fig. 9, with which are adapted to engage teeth43, see Fig. 11, on the face of the other member 41, which is madein theform of a disk and is keyed to the shaft'38 so as to rotate therewithand slide thereon. The disk 40 may be designated the fixedmember, andthe disk 41 the movable member of the clutch. The member 41 is adaptedto be engaged with the member 40 by a spring 44, see Fig. 9, whichencircles the shaft 38 between said member and a collar 45 fast on saidshaft.

Provision is made for disengaging the member 41 from the member 40 andalso for stopping rotation of the crank shaft 38. This result may beaccomplished by a crank or arm 50 fast on a rock shaft 51, provided witha treadle 52, said crank or arm having a cam, wedge or inclined portionor finger 53, see Figs. 9 8:10, which cooperates with a lug orprojection 54 on the face of the member 41, so that when the cam arm orcrank 50 is move'd'forward toward the clutch members 40, ,41, the narrowend of the cam or wedge will ass between said clutch members suflit fyto be engaged by the lug 54 on the member 41, and as the shaft 38continues to be revolved, said lug will travel up the inclined face ofthe wedge or cam, and force the member 41 back on the shaft 38 againstthe action of the s ring 44, until the member 41 is disengaged f fom themember 40, and at or about the time this takes lace, the shaft 38 isarrested in its rotation y a lug or projection 57 on the member 41engaging a projection or stop piece 58 on the crank 50.

The clutch member 41 is provided with two lugs or projections 57substantially diametrically opposite, so that the crank shaft 38 may bearrested at each half revolution.

The shaft 39 may be driven from the main shaft 15, which may beaccomplished by a link chain 60, passed about a sprocket wheel 61 on theshaft 15 see Fig. 12 and about a Y sprocket wheel 62 on the shaft 39.

The flexible apron or bed 25 has coiperating with it a feed or pinchroll 65, preferably fluted as herein shown and having its shaft 66journaled in the side frames i, j, and provided with a gear 67 withwhich meshes a gear 68 on the upper roll 32, when the bed is in itsforward or operative position shown in Figs. 1, 2 & 3.

said shaft by clutch mechanisms, which may be of any suitableconstruction and which are herein shown, see'Fig. 5, as two slidingmembers or shoes 73, 74, connected by levers 75, 76, to a sleeve 77fitted to slide over hubs 78 7.9 keyed to the shaft 66, and providedwith flanges 80, 81, to which latter the shoes 73, 74 are connected bybolts 82, 83, extended through slots 84, 85, in'the flanges 80, 81. Thesleeve 77 is actuated by a lever 87, pivoted at 88 to a bracket 89attached to the framework of the machine. The lever 87 is provided witha fork 90 to engage a groove 91 in the sleeve 77, and said lever hasattached to its upper end a slipper bar or rod 92. extended across thefront of the machine and sliding in suitable bearings carried by theframe work of the machine, whereby the operator can actuate the clutchmechanisms from either end of the machine or from the middle of thesame.

The sprocket Wheel 71 is connected by a link chain 94, with a sprocketwheel 95 fast on the main shaft 15, see Figs. 4 and 12, and the sprocketwheel 72 is connected by a link chain 96 with a sprocket wheel 97 on ashaft 98, suitably supported by the frame-work of the machine andprovided with a gear 99, which meshes with a gear 100 fast on the mainshaft 15. It will be observed that the sprocket wheel 71, is drivendirectly from the main shaft 15, and is rotated in one direction whichmay be to feed the hides or skins into the machine, and that thesprocket wheel 72 is rotated in the opposite direction, by theintermediate gear 99, which may be to feed the hide or skin out of themachine.

By moving the sleeve 77 to its central position both sprocket wheels 71,72 may be rendered loose on the shaft 66 and the feed roll therebyrendered stationary.

In operation with the machine herein shown, the working cylinders ortools a are moved bodily in a circular path by the rotation of thecarrier 6, f, whlch is effected by the pinion 17 and gear 18. By thisbodily movement the working tools or cylinders a are successivelybrought into operative position with relation to the bed 25. During thebodily movement of the working rolls or cylinders a, they are revolvedat a substantially high speed, which is effected by the pinions 17, 19,gear 21. shaft h, gear n and pinion m. The revolving cylinders or rollsa engage the hide, skin or leather lying on the bed 25, which isautomatically brought into its operative position shown in Figs. 1, 2and 6, by the operator depressing the foot treadle 52 so as to rock thetreadle shaft 51. andwithdraw the cam finger 53 from engagement with theclutch member 41, thereby permitting the spring 44 to move the clutchmember 41 into engagement with the clutch member 40 and thus couple thecrank shaft to the shaft 39, which is continuously driven from the mainshaft by the link chain 60.

Then the crank shaft 38 is coupled to the shaft 39, the crank shaftmakes a half revolution and through the cranks 37 and links 36, turnsthe levers 34 on their pivots so as to move the upper end of said leverstoward the path of movement of the operating cylinders or rolls (L,thereby bringing the bed into its operative position, at which time thegear 68 is in mesh with the gear 67.

After the foot treadle 53 has been depressed to couple the crank shaft38 to the shaft 39, and the crank shaft has been set in motion, theoperator may remove his foot from the treadle and permit the crank orarm to drop by gravity or be forced by a suitable spring (not shown), sothat the narrow end of the cam finger 53 will be inserted between theclutch members 40, '41 sufficiently to be engaged by the lug 54, so thatat or about the time the crank shaft has made a half revolution, the camfinger 53 will disengage the clutch member 41 from the member 40 and thelug or projection 57 will engage the stop finger or projection 58,thereby arresting the movement of the crank shaft 38 with the bed 25 inits operative position.

While the bed is in its operative position, the hide or skin (notshown), but which is placed or thrown on to the bed and over the roll32, when the bed is in its outward or inoperative position, is actedupon by the working tools or cylinders a as the latter are successivelybrought into engagement with the same, and said hide or skin may be fedout of the machine by the operator moving the shipper rod 92 so as tocouple the sprocket \lvheel 72 with the shaft 66, as represented in If aportion of the hide or skin should not be satisfactorily worked by onetool or cylinder, the operator can feed the hide or skin into themachine so that the part of the hide or skin which was not properlyworked. by one tool or cylinder, may again be properly positioned to beworked by the next cylinder or tool a. This feeding-in of the hide maybe accomplished by the operator movingthe shipper rod 92, so as touncouple the sprocket wheel 72 from the shaft 66 and couple the sprocketwheel 71 therewith.

With the clutch in its central position, the bed is stationary and thehide may be worked upon as long as desired.

The blades or working edges of the different rolls a, may be ofdifferent pitches, angles or arrangement (see Fig. 1), so that theblades of one roll may pull upon the hair in one direction and theblades of the next roll may pull upon the hair in a different directionand the blades of the next roll may pull in still a diflerent directionand so on, whereby those hairs which. may not be removed by the bladesof one roll pulling upon the same in one direction, will be removed bythe blades of the succeeding rolls pulling upon thehair in differentdirections, thereby removing the hair in a most effective manner.

After the hide or skin. has been treated as described, the bed. may bemoved back or away from the path of movement of the cylinders a by theoperator again depressing the foot treadle, so as to withdraw the camfinger 53 from engagement with the lug 54 and permit the crank shaft 38to be connected with the shaft 39, and when this occurs the operator mayrelease the foot treadle, and thereby place the cam finger 53 intoposition to disconnect the crank shaft 38 from the shaft 39 and stop thelug 58 to engage a lug or projection 57, at or about the time the bedhas been moved into its outward or inoperative position.

We have shown one form of bed which may be of rubber and thereforeelastic so as to enable the hides or skins to be effectively unhaired,but we do not desire to limit our invention in this respect, as otherforms of beds may be used according to the particular kind of work to beperformed, as for instance fleshing, working out, putting out, scouring,etc.

YVhen the machine is used for unhairing, it may be provided with a waterdistributing pipe 110 extended across the machine above the bed when thelatter is in its operative position, and perforated on its under side soas to shower or spray a stream or sheet of water down over the portionof the hide or skin from which the hair is being removed. The pipe 110may be connected by the pipe 112 with a suitable source of supply.
